PATENTEDUEE25I973 3 780 810 SHEEI 2 BF 3 1 HORSESHOES The inventionrelates to horseshoes.

According to one aspect of the invention there is provided a method ofmanufacturing a horseshoe which comprises casting it of a metal andsubsequently annealing.

Such metal may be carbon steel and the casting may comprise shellmoulding. The annealing may be at a temperature of the order of 960C,for at least two hours followed by cooling in the furnace.

According to a further aspect of the invention there is provided a metalhorseshoe which has been cast and annealed.

Preferably the metal comprises a carbon steel having the followingspecification in parts by weight:

Carbon 0.08 to 0.17 Nickel 0.15 maximum Silicon 0.35 Chromium 0.15maximum Manganese 0.80 Molybdenum 0.10 maximum Sulphur 0.04 maximum-Copper 0.10 maximum Phosphorus 0.04 maximum Tin 0.01 maximum Thehorseshoe may include any one or combination of the following features:I

l. A full width of material in the toe with the shoe tapering in theheels.

2. A heel formed round through 90 with or without a toe piece.

3. A ground engaging surface formed with serrations to reduce skiddingin use.

4. Clips cast in the shoe.

5. A seating or champher of the inner edge of the hoof engaging surface.

6. A three quarter fullering without any deformation.

7. A heel which is cut away at the inside or bevelled.

8. A ground engaging surface of which the inner edge is champhered inconcave form.

It has been found that utilising a carbon steel as hereinbeforedisclosed and using a shell moulding technique a horseshoe can bemanufactured having a fine grain size after annealing to providesufficient tensile strength and which is sufficiently ductile for normaluse. By fine grain size is meant having a fully recrystallised equi-axedgrain structure without any grain growth having taken place inannealing.

By utilising casting for manufacture an extremely good finish can beobtained with a combination of features which cannot be economicallyprovided in a horseshoe manufactured by conventional techniques.

The foregoing and further features of the invention may be more readilyunderstood from the following description of some preferred embodimentsthereof, by way of example, with reference to the accompanying drawings,in which:

FIG. 1 is a plan view of the ground engaging surface of a horseshoewhich has full width at the toe and is tapered at the heels;

FIG. 2 is a side elevational view of a, horseshoe formed with a heelnormal to the main body of the shoe;

FIG. 3 is a side elevational view of a horseshoe formed with a heel anda toe both normal to the main body of the shoe;

FIG. 4 is a side elevational view'of a horseshoe with a serrated groundengaging surface;

FIG. 5 is a side elevational view of a horseshoe formed with a clip atthe toe of the shoe;

FIG. 6 is a front elevational view of the horseshoe of FIG. 5;

FIG. 7 is a plan view of the foot engaging surface of a horseshoe formedwith a seating or champher on its inner edge;

FIG. 8 is a sectional view along line AA of FIG. 7;

FIG/9 is a plan view of-the ground engaging surface of a horseshoeformed with a three quarter fullering and a concave champher on itsinner edge;

FIG. 10 is a sectional view along the line BB of FIG.

FIG. 11 is a sectional view similar to FIG. 9 of a prior art horseshoe;

FIG. 12 is a plan view of a horseshoe with the inside of the heels cutaway, and

FIG. 13 is a side elevational view of a horseshoe with bevelled heel.

Before considering the drawings in detail the method of making all thevarious horseshoes will be considered. All the shoes are manufacturedutilising carbon steel having a composition as follows in parts byweight:

Carbon 0.08 to 0.17 Nickel 0.15 maximum Silicon 0.35 Chromium 0.15maximum Manganese 0.80 Molybdenum 0.10 maximum Sulphur 0.04 maximumCopper 0.10 maximum Phosphorus 0.04 maximum Tin 0.01 maximum The shoesare all cast utilising the shell moulding technique followed byannealing at a temperature of 960C and holding or soaking at thistemperature for two hours, followed by cooling in the furnace.

Referring now firstly to FIG. 1 of the drawings there is shown ahorseshoe which has a full width of material at the toe 11 and in whichthe heels 12 are tapered.

FIG. 2 shows a horseshoe formed, in the casting, with a heel 13 which isnormal to the remainder of the body of the shoe.

FIG. 3 is a similar shoe to that illustrated in FIG. 2 with the additionof a toe portion 14 which is normal to the remainder of the body of theshoe.

FIG. 4 shows a horseshoe with a ground engaging surface 15 which isserrated so as to prevent or reduce skidding, in use.

FIGS. 5 and 6 show a horseshoe which is formed, in the casting, with aclip 16 at the toe of the shoe.

FIGS. 7 and 8 show a horseshoe formed with a seating or champher 17'formed at the inner edge of the foot engaging surface of the shoe.

FIGS. 9 and 10 show a horseshoe formed with a three quarter fullering 18during the casting. It should be noted that the outer edge 19 of theshoe adjacent fullering 18 is not deformed. In contrast FIG. 11illustrates a sectional view similar to FIG. 10 of a prior art horseshoein which the fullering 18 has been produced by punching. It will be seenin this shoe the outer edge 19' has been deformed by the punchingoperation. In FIGS. 9 and 10 the inner edge of the ground engagingsurface is champhered at 22 to provide a self-cleaning shoe.

FIG. 12 shows a horseshoe in which the heels 20 are cut away and FIG. 13shows a horseshoe in which the heel is bevelled at 21.

The features illustrated singly in the drawings may be combined in somecases where appropriate. All the features illustrated are desirable fordifferent uses andall are expensive, difficult or impossible to produceutilising conventional horseshoe manufacturingtechniques.
